"CE-V.R" is not a file extension, it stands for "Cracked Edition (by team) V.R". Files are often *.zip or *.rar files that you need to decompress, then to read the .nfo or .txt (text file with instrutions, informations...), to follow instrucions to install etc (most of the software/plugins provided by team V.R doesn't need keygens and stuff like this, just install and enjoy !)

Only Microsoft knows why the file extensions are hidden by default. :/ It only makes people who are not very proficient with computers even more confused. I untick that damn stupid thing on every Windows OS I have a close encounter with.

Thanks a lot for all your replies and the great reactivity.
I know that they are Rar files but when i unrar them i've got that, for example : FXpansion BFD Jazz Maple-V.R and my mac describe it as a "SD2 split" file.....?
